JPA Tutorials

JPA Tutorials and Example:

Here we are providing easy to learn JPA tutorials. All the JPA concepts
discussed here are supported by running example code. You can download the
code and experiment with JPA examples easily and in very less time.

What is JPA?

The Java Persistence API or JPA for sort is one to the specification of
JEE5, which allows the programmer to develop the persistence layer for
their desktop and web applications. JPA is developed to ease the
development of persistence layer and it has also standardized the Java ORM
technologies.

Let's get started with JPA.

JDBC vs ORMIn this section we will examine the differences and similarities between JDBC and ORM technologies. Both these technologies are used to save the data into persistence storage for future reference.

JPAThis section introduces you with the Java Persistence API (JPA). We will learn the benefits of JPA specification. We will also list down the ORM frameworks that can be used with the JPA specification.

JPA ArchitectureIn this section we will discuss the architecture of JPA specification. Java Persistence API or JPA for short is a lightweight,
POJO-based Java framework to persist the Java Objects to the relational database.

JPA Features
In this section we will
discuss about the features of JPA (Java Persistence API).
